- What changed
- Independent reproduction confirms chain-of-thought entropy shape predicts LLM correctness, while total entropy drop magnitude is setting-dependent.
- Why you should care
- Final-step entropy outperforms binary shape flags in most test cells.
- Your move
- Reconsider. Use final-step entropy instead of binary shape flags for reliability.
- What to watch next
- Independent validation of final-step entropy as a reliability signal across diverse model families.
